If your vision is 20/200 with glasses (Best Corrected Visual Acuity, BCVA), then Lasik and other forms of refractive surgery will not resolve your underlying problem.

Amblyopia, often called "lazy eye", is commonly caused by strabismis, when the eyes are not correctly aligned such as crosseyed. During the developing years the brain is confused by the misaligned images and literally ignores the information from one eye. This can cause low quality vision even if light entering the eye is properly focused with glasses, contacts, or Lasik. Amblyopia is a neurological process that does not relate to the optics of the eye, therefore cannot be resolved by changing the eye's optics.
